Version 4.5 of the AmiSSL library for Amiga based operating systems is released. Version 4.x is a new major release which comes with full compatibility to the OpenSSL 1.1.x line which includes important security related fixes and comes with new encryption ciphers which are required nowadays to connect to modern SSL-based services (e.g. HTTPS). However, due to fundamental changes in the API between the old AmiSSLv3 and new v4 versions and the large changes between the old OpenSSL 0.9.x and the new OpenSSL 1.1.x line applications have to be recompiled with the updated AmiSSL SDK to take full advantage of the modernized OpenSSL 1.1.x API. Besides that fundamental change, AmiSSLv4 can be installed on top of a AmiSSLv3 installation while still ensuring that applications compiled for AmiSSLv3 will continue to work properly.
